Detailed Description

Abstract representation of a central body.

The CentralBody class provides a common interface to the group of central body objects (Planet, moon, asteroid, etc.) The central body group stores the pertinent parameters that affect the operating environment of a spacecraft. This includes the radius, mass, gravity field, atmosphere characteristics (if they is an atm), and relationship to other central bodies (such as from the sun, or a moon to planet).
